Single column anti-tilting device

A single column anti-tilting device resolves the problem that a single column is easy to tilt or fall down, and is characterized in that the single column anti-tilting device consists of a column outer tube (1) and a slide drawing bar (2), an oblique slide groove (3) is arranged on the column outer tube (1), an anti-loosing pin (4) is arranged in the oblique slide groove (3), and the column outer tube (1) is fixed with the slide drawing bar (2) via bolts (5). The single column anti-tilting device has the advantages that the anti-tilting device is safe and adaptable, is flexible in combination and prevents the single column from tilting or falling down or guarantees the single column to be perpendicular, and is particularly adaptable to preventing the single column tilting and falling down and guaranteeing the column to be perpendicular.
